CVE-2025-52986

  2. Vulnerabilities (CVE)
  3. CVE-2025-52986
A Missing Release of Memory after Effective Lifetime vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low privileged user to cause an impact to the availability of the device. When RIB sharding is enabled and a user executes one of several routing related 'show' commands, a certain amount of memory is leaked. When all available memory has been consumed rpd will crash and restart. The leak can be monitored with the CLI command: show task memory detail | match task_shard_mgmt_cookie where the allocated memory in bytes can be seen to continuously increase with each exploitation. This issue affects: Junos OS: * all versions before 21.2R3-S9, * 21.4 versions before 21.4R3-S11, * 22.2 versions before 22.2R3-S7, * 22.4 versions before 22.4R3-S7, * 23.2 versions before 23.2R2-S4,  * 23.4 versions before 23.4R2-S4, * 24.2 versions before 24.2R2, * 24.4 versions before 24.4R1-S2, 24.4R2; Junos OS Evolved: * all versions before 22.2R3-S7-EVO * 22.4-EVO versions before 22.4R3-S7-EVO, * 23.2-EVO versions before 23.2R2-S4-EVO, * 23.4-EVO versions before 23.4R2-S4-EVO, * 24.2-EVO versions before 24.2R2-EVO,  * 24.4-EVO versions before 24.4R2-EVO.

Summary
  • (es) Una vulnerabilidad de falta de liberación de memoria tras el tiempo de vida útil efectivo en el daemon del protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un usuario local con pocos privilegios afecte la disponibilidad del dispositivo. Cuando se habilita la fragmentación RIB y un usuario ejecuta uno de los varios comandos "show" relacionados con el enrutamiento, se pierde cierta cantidad de memoria. Cuando se consume toda la memoria disponible, rpd se bloquea y se reinicia. La pérdida se puede monitorizar con el comando de la CLI: show task memory detail | match task_shard_mgmt_cookie, donde se observa que la memoria asignada en bytes aumenta continuamente con cada explotación. Este problema afecta a: Junos OS: * todas las versiones anteriores a 21.2R3-S9, * versiones 21.4 anteriores a 21.4R3-S11, * versiones 22.2 anteriores a 22.2R3-S7, * versiones 22.4 anteriores a 22.4R3-S7, * versiones 23.2 anteriores a 23.2R2-S4, * versiones 23.4 anteriores a 23.4R2-S4, * versiones 24.2 anteriores a 24.2R2, * versiones 24.4 anteriores a 24.4R1-S2, 24.4R2; Junos OS Evolved: * todas las versiones anteriores a 22.2R3-S7-EVO * versiones 22.4-EVO anteriores a 22.4R3-S7-EVO, * versiones 23.2-EVO anteriores a 23.2R2-S4-EVO, * versiones 23.4-EVO anteriores a 23.4R2-S4-EVO, * versiones 24.2-EVO anteriores a 24.2R2-EVO, * versiones 24.4-EVO anteriores a 24.4R2-EVO.
